Mathematics: Problem 3 Anh, Bill and Cathy each think of a positive whole number less than 1000. • Anh says, My number is bigger than 500 and divides by every integer from 1 to 10 except for 7. • Bill says, My number divides by every integer from 1 to 10 except for 9. • Cathy says, You have both done better than me, but I can see that if we added our three numbers together, the total would divide by all the numbers from 1 to 10. What numbers from 1 to 10 does Cathy s number not divide by?

Cathy's number is not divide by 7 and 9

Step-by-step explanation:

Anh’s number is divisible by all numbers from 1 to 10 except 7.

Hence, Anh’s number is 8*9*10 = 720

Bill’s number does not divide by 9, hence his number would be = 3*8*5*7 = 840

The sum of numbers of all three is divisible by all numbers between 1 to10

So the sum number is = 10*9*8*7 = 5040

Number of Cathy = 2520 – 720 -840 = 960

960 is not divisible by 7 and 9
